Hello,
I am wondering which options we have for a Proxmox VE machine which has all VM located on a NAS (connected via NFS) to synchronize the startups and shutdowns of both system. I already searched here in the forum and also googled about the topic, without finding real solutions so far. Most of the time the "solution" would be to simply "wait for X seconds" on startup of PVE.
In the follwoing, I am only talking about the problematic cases:
Thanks in advance,
Thomas
P.S. Some of the sub-points in my text are printed in bold. I did not make them bold and was not able to remove it. Seems to be a bug in the board software
I am wondering which options we have for a Proxmox VE machine which has all VM located on a NAS (connected via NFS) to synchronize the startups and shutdowns of both system. I already searched here in the forum and also googled about the topic, without finding real solutions so far. Most of the time the "solution" would be to simply "wait for X seconds" on startup of PVE.
In the follwoing, I am only talking about the problematic cases:
- PVE + NAS are running --> NAS shuts down
- In this case the NAS should trigger PVE to also gracefully shutdown.
- Which options do we have here?
- Shutdown command via SSH
- Sending a "power off" via IPMI
- Any better ideas?
- PVE is running, NAS is powered off or still booting
- Regarding all the information I found so far the NAS will usually startup much slower than PVE. This means that PVE has to wait until its Storage (NFS) is available.
- It could also happen that the PVE machine is started, but the NAS is still powered off.
- For my current knowledge, PVE only has a time-based "wait" here.
- Which options do we have to force PVE to wait longer, in case the NAS needs some more time to start up?
- Is there a possibility to let PVE wait, until the NFS storage is available?
- Maybe, a cron job which cyclically checks the availablity of the storage?
- PVE is running, NAS wants to reboot
- The scenario could be handled with the points above, however, it could also be an option to simply "pause" all VMs here and continue them after the NAS is available again.
- Any thoughts on this?
- PVE + NAS are running --> The NAS system crashes
- What will happen to PVE if the NFS storage drops out (HW defect) during runtime of the VMs located on this storage?
- Will PVE crash? Will PVE halt/stopp/pause the VMs?
- Will data definitely be corrupted?
- What best practices do you have for this scenario?
Thanks in advance,
Thomas
